SERVICE-DOOR To all witoin it may concern:

j'Be i known that J. MATcrr- E'rrE, a citizen of .the United States, residing at Milwaukee, in the..county of Milwaukee and State of Wisconsin, have'invente'd a certain new. and useful Improvement" in Service Dools, (Casei6 of which the folthis specification. I I My invention relates to lowing. is-a full, clear, concise, and exact. description, reference being bad tothe ac-' companying drawings, forming. a part of service doors.

The object of the invention-is to provide r an inexpensive'and eflicient service :door .for I the same general class of 'serviceas that dicated in my copending application, Serial No. 852,533, filed July 23rd, 1914-now patform a part of t ent No. 1,222,964 dated Apr. 17,- 1917; ;A further object is. to provide jg'ravit control mechanism fora lock suitable inservice cabinets orthe like.

building or the'like, and consists of a cabinet 1 inclosed orsurrounded by the top and bottom rails 2 and 3 respectively, and thehinge and lock stiles Land 5, respectively. It 1s not essential that these parts be madeof separate pieces, and my designation of them asseparate parts of the door, is merely for the purpose of designating their position and use, and I intend thereby to desiga number-of smaller compartments of less extent. I In Fig. 3 I- have illustrated a form of door iniwhich a number of larger compartments,-

10, 11 and '12, and a plurality'of smaller compartments, 13 and 14:, are provided,

These chambers are formed bypartitionsin thecabin'et' itself and adoor closes theoutside of each individual compartment,

net. In the door shown in Fig. 1, the com- 'partments, 6, 7, '8 an d 9,are closed .by the] doors, 16, 17, 18 and" 19frespectively, and in 1 ,-.1 1,- 12, 13. and 14, are closed ontheoutside bythe doors, 20, 21, 22, 23.and' 24, re-

with a suitable lock, preferably of the-type spectively.'. The inner door 15 is provided which can be released only from the outside easily operable in opening and closing.

the" formshown in Fig. 3', compartments,

ofthe cabinet, as by means of the handle; 25. Each'door is suitablyhinged so as to be The cabinet 1' is secured to the frame members of the door, and the-junction of the cabinet and. these frame members is finished oil by the angle molding 28 on each j side of the main door.

The door 16, on the outside of cabinet 6',

'is provided with a handle 26 forming part of a suitable combination lock. The doors on: the other cabinet are provided. with han- I dles27, which are connected with suitable spring'latches, aswill be described later.

Upon the rear of. the cabinet, small sight openin s 29 for each one. of the compartments, is cut through the'marginal ortion' of the cabinet,- adjacent the edge of t e door 15. Back of each sightopenmg 29, a target 30 is supported in such relationas toswing into and out of indicating position ap prise the housewife or maid upon the lnslde of the main door, of the condition of the cabinetsthat is, whether they are filled or empty. A fin or cam 31 is secured to the outer compartment door as, for instance the door 17 shown in Fig. 6, and a similar fin or cam member 32 is secured to'the single inner door 15. The bracket 33 is secured to the side of the cabinet, as shown in Fig 7, so that the arm or lever 34, which is pivoted to the bracket at 35, and which bears the target 30 at one end thereof, will be in suitable position to be operated by the cams 31 and 32. The pivoted arm 34 is provided at its outer end with a lateral extension 36 which is long enough to extend within the path of the cam 31. The opposite end or the arm 34 is similarly provided with an extension 37, which, as shown in the particular embodiment illustrated in Fig. 7, may consist of an extension of the target 30, which is secured to the end of the arm 34. The extension 37 projects into the path of the 'cam 32. The bracket 33 is provided with a lateral extendingportion 38 which is suitably slotted to allow swinging of the arm 34 which projects through the slot. The outer end of the arm is provided with a lug 39 and a spring 40 connects the lateral ex tension 38 and the lug 39 so as to give the indicating arm 34 a snap action after it is once pushed slightly past the central or neutral position. The pivot 35 is so positioned with respect to the cams 31 and 32, that the ends of the arm 34will be moved up and down to bring the projections 36 and 37 alternately into and out of the paths of the cams 31 and 32respectively.

I shall now describe the gravity lock con trol which I prefer to employ with this type of service door. shall describe the lock and control employed and illustrated spe cifically with respect to the compartment 7.

A suitable spring latch 41 is secured to the inside of the door 17 adjacent the margin thereof so that the projecting bolt 42, which is provided with an inclined surface on its inner face, may engage the edge of the cabinet and form a catch to prevent the door 17 from opening after the spring bolt 42 is moved into place, as shown in Fig. 5.

The top of the bolt 42 is providedwith a notch 43 and the front part of the boltjs provided with an inclined face 44. A. vertical controlling bar 45 is mounted on the edge 46 of the cabinet 1, being loosely secured to this edge by means of headed pins 47 and 48, which pass through the slots 49 and 50 in the bar itself. The upper end of the controlling bar 45 is provided with a detent 51 for engaging the notch 43 in the top of the bolt 42. The bottom of the bar 45 is provided with a foot or extension 52, which Lean-cos partment, and a counterbalance extension 57 for holding the pan 53 normally in the level position. When an article is deposited in the pan 53', the pan tilts downward until it engages the projection 58 in the bottom 59 of the compartment. The controlling bar 45 normally resting upon the edge of the pan, loses its support and drops downward, causing the detent 51 to engagethe notch 43 in the bolt 42. lit will then be impossible to withdraw the bolt 42 and the compartment 7 is inaccessible from the outside. As soon as the housewife or maid opens the inner door 15 and removes the article from the pan 53, the counter balance 57 will raise the controlling bar 45 and release the bolt 42 so that the same may be withdrawn and the door opened to permit access to the compartment 7.

The signaling mechanism operates in conjunction with the above as follows 'When the parts are in the position shown in Fig. 6, theouter door 17 may be opened by the purveyor to place a package within the compartment. As the door 17 is opened,

the cam 31 engages the projection 36 and throws the arm downward past the center point, where it remains under. the influence of the spring 40 holdingthe target 30 in indicating position befbre the aperture or sight opening 29. 'As the package is deposited in the pan 53, the same moves downward overbalancing the weight 57. The controlling bar 45 drops at the same time, since it loses its support from the rim of the pan 53. When the door 17 is closed by the purveyor, the bolt 42 which is spring pressed, noses under the .detent 51 raising the same to the point where it will drop into the notch 43 and will again prevent withdrawal of the bolt 42.

The upper compartment door 16 (see Fig. 1) is provided with a combination lock which is preferably not provided with gravity control.

. The upper compartment 6 may be reserved for such uses as handling laundry. The

laundry is placed in the compartment (Hey the housewife and the driver being provided with the combination of the lock, may re-' move the articles and when the work on them has been finished. they are returned in the same manner. The occupant of the premises is apprised of the removal of the articles to be laundered by operationot the indicator and as the indicator will be set back to the non-indicating position as soon as the inner door 15 is opened, the occupant will again be apprised of the.return of the laundered articles by" setting ofthe proper indicator. The small compartments may be each provided with a separate indicator if so desired.

I have shown the cabinet 1 as constructed of sheet metal. It is to be understood that the frame part of the door may also be made 'between the inside and the outside sheets of metal.
